If we are compatible or good in long term relationship (He born in year 1975 and i'm in 1977

Hi,

I wonder if we are compatible.

His birthday is on 29 Feb 1975 and mine is on 24 Sept 1977. May i know what element are we? It is true that if element clash we are not advisable not to be together?

Because after we read a an article and found out that if we are together we will shorten our happiness as clash.

May i know if it is true?

Thanks.
